Anybody,
no matter what i change or try to command the actual AFR will not change.
I added 20% across the higher half of the Main VE and nothing happened.
Whats the deal?
I have ran out of ideas and im clueless. Need help.
Here is the tune and a log.
Tryin to go Speed Density, Tried to go back closed loop from a old tune that worked. It had no changes and now its lean and not richening up when the PE settings are met..

You need to command something other than 14.68 in those cells in table B3605. Even though your in speed density, commanding 14.68 will result in defaulting back to using your trims (its a weird EFILive thing). Change your 14.68's to 14.75's or something then adjust your VE table accordingly and see how that works. If i remember it mentions something in more detail about this in the Closed loop to open loop tutorial.

Edit -> Configure display units
Then adjust the specific data, rows, and columns between metric and imperical accordingly. Some tables you may want to have a combination of Metric AND imperical. Just right click on the table line you want to make adjustments to and change either the rows, columns, or data........or any combination of the three. For example in table B5911 you may want the column to be metric (grams/Cylinder) and rows to be imperical (fahrenheit).

I just make it all imperial and then when I see something that needs to be metric I change just that back to metric.

we looked for air leaks but no luck. We are stumped? im going to pull the cai off today and see if it might be leaking from a boot! no exhaust leaks at all! It was running fine then he tried to smooth out some lean spots and now the whole table goes lean. I roll on the throttle and it richens up then right back to lean!

when i did the free air calibration i checked for an exhaust leak just to rule that out and we checked the fuel pressure.
Whippled: i have B3605 setup similar to the tutorial. i do see i need to have a small ramp in the fuel tho. its 14.62 like the tutorial shows.
i just changed aome stuff in the tune and goin to try this again tom i guess....
